Had some problems withdrawing items. I had "withdraw 1" on my list twice, and only the second one worked. Just clicking on the item wouldn't put it into my inventory. No idea why - bug report submitted.
Is it possible to customise what you call the tabs. For example I want one called "food" - but this isn't an option on the list. (Cooking could be used as an alternative - but this isn't how I think of the tab contents).
